Technical background
Traditional single-phase converter, for example the spy open flat 10-337034 communique disclosed " sinusoidal wave input single-phase rectifier loop " and, real open clear 64-50686 communique disclosed " commutating circuit " and, the spy opens the single-phase semi-bridge formula converter loop of flat 2-237469 communique disclosed " adopting the supply unit of PWM control " etc.Figure 15 represents the formation of this traditional single-phase semi-bridge formula converter loop.In this semibridge system converter loop, the side of interchange incoming line that bridge-type is connected with the capacitor input rectifying loop of four diode 54a-54d is connected with reactor 53, and disposes in parallel with diode 54c, 54d and opposite polarity thyristor 55a, 55b.
The alternating voltage of importing via noise filter 252 from AC power 51 converts direct voltage to.Drive loop 65 by power pack (CT) 56, target output voltage 58, output voltage error amplifier 59, power supply synchronization loop 60, multiplier 61, current error amplifier 62, triangular wave 63, comparator 64 and thyristor PWM, PWM drives thyristor 55a and 55b, carries out power-factor improvement, supply harmonic inhibition, direct voltage adjustment.The detection of the input current of one of Control Parameter when PWM drives thyristor 55a, 55b is carried out by the CT56 that is arranged on the AC side incoming line.
In this semibridge system converter loop,, use the high frequency carrier that has more than the carrier frequency 20kHz to carry out PWM and switch for the switch speed of accelerating thyristor 55a, 55b, the variation and the miniaturization reactance device 53 of accelerating voltage electric current.Because the influence of this high dv/dt and distribution impedance might produce the public system noise of hundreds of kHz to a MHz more than hundred and have influence on other device.When being applied to household appliances such as air-conditioning, relevant for the rules of public system noise such as noise terminal voltage, must be controlled in the fixed reference range.Thereby, disposed large-scale noise filter 52 in the former single-phase semi-bridge formula converter loop, so that suppress the public system noise.
The reactor installation method and the cooling means of traditional converter device are described below with reference to Figure 16,17.Figure 16 is that the thyristor that passes through before having carries out that harmonic wave suppresses, the simple circuit figure of the air-conditioning of the converter device of power-factor improvement.Figure 17 is the installment state of the reactor of the converter device in the air-conditioning before the expression, the profile of observing from the off-premises station top of air-conditioning.
Among Figure 16,101 is thyristor, and 102 for carrying out the reactor of harmonic wave inhibition, power-factor improvement, 103 for being connected electrically to reactor 102 in the lead on the main circuit substrate 104, and 113 is electrolytic capacitor, and 116 is diode, 123 is bypass resistance, and 124 is resistance.Among Figure 17,105 are the radiator that is fixed on the main circuit substrate 104, promotion is installed in the heat generating component heat radiation on the substrate, 106 is outdoor fan, 107 is off-premises station, 108 is the heat exchanger of the outdoor fan 106 upstream sides configuration in the off-premises station 107, and 109 is the electrical box with bag in main circuit substrate 104 and the reactor 102, and 110 is direct wind from outdoor fan 106,111 is the ventilation hole that forms on the electrical box, and 112 is the gentle breeze that flows according to pressure differential.
In the reactor 102 in the converter loop that improves the air-conditioning power factor that the simple and easy loop diagram of Figure 16 is represented, by the compressor motor that inverter drives, the peak value of flowing through reaches the big electric current of 30A.Thereby the size of reactor and caloric value are all very big, it is very heavy that weight also becomes, can't be installed on the main circuit substrate 104, as shown in figure 17, be connected electrically on the main circuit substrate 104 that thyristor 101 and electrolytic capacitor 113 etc. are installed by lead 103.In addition,, thereby be configured in the place that obtains gentle breeze 112 by the interior outdoor fan 106 of off-premises station 107 and pressure differential,, carry out natural cooling as near the ventilation hole etc. because thyristor 101 is not connected with radiator 105.

Thereby, must be installed in machine in the narrow electrical box as this control device of air-conditioning, have the restriction near the structure design that size is big, reactor can only be installed in ventilation hole, and in the electrical box temperature rise, assembly accelerated deterioration such as the electrolytic capacitor on the control basal plate and make the low problem points of life of product.
In addition, the converter device of the power-factor improvement of loop shown in Figure 17 representative, because thyristor 101 utilizes high carrier wave (about 20KHz) to carry out PWM control, current/voltage sharply changes and the voltage oscillation of harmonic wave takes place, with circuit loop as sky alignment space radiation noise.Thereby existence antenna when lead 103 lengthenings becomes big, the problem points that the radiation noise content also increases.
Thereby, the object of the present invention is to provide the single-phase converter loop that may make the substrate size miniaturization and reduce cost.
